Following are a number of back-translations of Luke 18:17:

• Noongar: «Remember! The person who does not accept the Kingdom of Heaven like a child, he will not go in.'» (Source: Warda-Kwabba Luke-Ang)
• Uma: «Truly I say to you: If you do not submit to God like children, you will not become his people in his Kingdom.'» (Source: Uma Back Translation)
• Yakan: «Truly I tell you,’ said Isa, ‘if the trusting of a person in God is not like the trusting of children, that person will really not be included in God’s ruling.'» (Source: Yakan Back Translation)
• Western Bukidnon Manobo: «It’s true what I say to you, that if there is a person and his trust in God is not like the trust of little children, then he cannot be ruled over by God.'» (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: «This that I tell you is true that if you don’t receive God’s ruling you like the way children receive, you will absolutely not be included there.'» (Source: Kankanaey Back Translation)
• Tagbanwa: «This which I will say to you is true, that whoever won’t make himself like a little child in his submitting to the rule of God, he won’t be able to enter that kingdom of his.'» (Source: Tagbanwa Back Translation)
• Gurung: » . . . whoever does not submit to God in the way children submit to their parents he will never receive the full blessing of God.» (Source: Warren Glover in The Bible Translator 1978, p. 231ff.)
• Italian (La Sua Parola è Vita): «Indeed, I tell you that those who do not accept the Kingdom of God as a present with the same humility of a child will never be able to enter it!” (Cotrozzi 2019 explains: «Although some thought of childlike trustfulness may be present, the focus more probably lies on humility as shown by the context with its rebuke of proud Pharisees in 18:9-14.»)
